Unfortunatelly for the researcher, modern construction technology mostly deals with heterogeneous multi-phase materials – composites, with different matrix materials, fillers, aggregates and admixtures.
The particle system method has numerous applications in material science, and in particular – in construction industry.
It can be seen from that summary that many methods in material science uses stochastic approach on different computational stages.
Determination of the size and volumetric content of the nanoscale modifier is a necessary prerequisite for the application of nanotechnology in materials science.

In recently years STM(Scanning Electron Microscope) has been widely used in surface science、materials science、 life science, etc.
